Another fun scenario: somebody crashes into a utility pole near your house, the power flickers, all your lights come on, the ceiling fans spin up 100%, and the ashes from your fireplace are distributed all over your house.
Or the lightning strike. Computer works, internet works, can't turn on any lights.
